Embodiment Construction
[0029] This embodiment is a three-phase separation device for an upflow anaerobic reactor, including four reflective collection plates 1 , a plurality of special-shaped separators 2 , scum separators 3 and UASB pools 4 . in:
[0030] The four reflective collection plates 1 are all trapezoidal plates. The lower bottom of each reflection collecting plate is equal to the side length of the inner wall of the UASB pool, and the upper bottom is 1 / 4 to 1 / 3 of the side length of the inner pool wall. Each reflective collection plate is located in the UASB pool 4, and the bottom edge of each reflective collection plate is respectively fixed on the middle part of the square UASB pool inner wall; said each reflective collection plate has an included angle α with the UASB pool inner wall surface, and the included angle α=120°~135°. The sides of two adjacent reflective collecting plates are connected by welding, so that the four reflective collecting plates all extend toward the central a...

The invention discloses a three-phase separation device for an upflow anaerobic reactor. Four reflecting and collecting plates all are located in a UASB pool, and an included angle alpha is formed by each reflecting and collecting plate and the inner wall surface of the UASB pool; a dross separator is arranged at the top end of the combined reflecting and collecting plates; and three special-shaped separators are arranged on the lower surface of each reflecting and collecting plate separately. According to the three-phase separation device for the upflow anaerobic reactor, the plate collision path of floating sludge is prolonged, the gas carried in the sludge can be effectively released and the gas release efficiency is improved. Effective separation of the carried gas and the sludge when water flow passes through the special-shaped separators and the sludge reflux rate is improved. Separation of dross and collection of the gas are achieved through the dross separator. The problems that an ordinary separator is low in separation efficiency, an air duct is easy to block and the dross is difficult to separate are solved; and the three-phase separation device has the characteristics of being simple in structure, easy to process and manufacture and low in engineering difficulty.
Description
technical field [0001] The invention belongs to the field of industrial wastewater treatment, and in particular relates to a three-phase separation device used in an upflow anaerobic reactor. Background technique [0002] The three-phase separator is a more commonly used dynamic separation equipment in industrial wastewater treatment. It has been more than 40 years since the technology was invented by Lettinga in the Netherlands in 1970. The traditional separator needs to be installed at the upper position of the upflow anaerobic reactor (UASB for short) to realize the separation of water, gas and solid (activated sludge and solid scum). However, the inverted "V" type three-phase separator used for UASB in the prior art needs a large amount of bracket consumables during engineering installation, and the three-phase separator is easy to collapse after long-term corrosion of the bracket, resulting in the external leakage of gas and sludge. The air duct is easily blocked due t...
